"AIR-LINE, OILER.

. Application filed September 30, 1927. Serial lie/223,067.

This invention relates to oiling devices, but more particularly to devices which are attached to air lines for introducing oil into the air current use for operating fluid actuated machines. I I

It is an object ofithis invention to eliminate interruptions in drilling and similaroperations, which must occur if the tool is tobe manually lubricated, and to introduce the oil into theair current uniformly and in,

suitable eration.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention consists of the combination of elements, features of construction and arrangement of parts having the general mode of operation substantially as hereinafter described and pointed out in the appended claimand illustrated in the accompanying drawings, in which Figure 1 is a top longitudinal view of an air line oiler, and

Figure2 is a longitudinal sectional view of Figure 1 taken on the line 2 -2 looking in the directionindicated by the arrows.

Referring more particularly to the drawings, A indicates a casing having a tubular wall or partition B which divides the interior of the casing A into an oilreservoir C and a passageway D. The reservoir C is so arranged as to surround the passageway D and the casing preferably has its outward shape substantially like that shown in the drawings so that it willsli'de easily over rough surfaces and be less likely to catch ontoprojections and irregularities when being drawn from place to place.

p In order to enable part of the pressure fluid flowing throu h the passageway D to i enter the reservoir 6 and exert a pressure on the oil in the reservoir, and to provide a quantitieswhile the tool is in opmeans of delivering this oil into the passageway, a hole F is drilled through the partition B at the place where an enlargement E is formed on the outer wallof the-partition B. Into this hole a cylindrical pin G is loosely fitted by passing it through the partly threaded opening H in the casing A. A threaded plug J is adapted to cooperate with the opening H and to limit the longitudinal movement of the pin G. The pin G is of.

such diameter that a slight movement is permitted between itand the walls of the hole F, and Ofsuch length that its lower end of the hole P.

rests on the bottom of the passageD and its upper end extends through the oil reservoir and into the opening In a similar manner a pin K is passed through a threaded opening L near the end of the oiler and loosely fitted in the holes 0 and P so as to extend into the oil at the bottom of the reservoir C and through the pas- I sageway D. Y I

Compressed a r or another pressure fluid is delivered to and from. the passageway D by the pipes Q and R- screwed into the oiler hole T is formed in a large plug V screwed into a threaded hole W in the casing A.

The oilhole is closed at its lower end by a a screen X held in place by a screw cap Y which is provided with an opening Z. The

oil is filtered and cleaned by the screen X before it enters the reservoir C.

The operation of the device is as follows: Pressure fluid such as compressed air enterat Q and into a threaded plug R respecing the passageway D from the air line Q, i

will, bythe pulsations caused by thecutoff and admission of pressure fluid in the tool to be oiled cause the pins G and K to vibrate transversely of the holes F and P respectively At the same time a portion of pressurefluid will" pass between the pins and the walls of the holes and create a pressure within the reservoir C'corres'ponding to the pressureinthe passageway D and some ofthe oil will be forced into the'clearance between pins and the walls of the holes and be squeezed out into the pressure fluid current by the vibrations of the pins G,

and K.

The great advantage of the pin K is found when the oiler is used in a vertical or nearly vertical pipe line. The oil in the reservoir C will then all flow to the left end of the oiler which will be the bottom of the oiler when the oiler is in a vertical position. In this position the oiler will function properly due to the fact that oil will still enter the g It will be readily seen that by having an opening L in the same side of the oiler as passageway D by way the oiler when it is necessary to remove pins G and K. A plug L normally closes the hole L. r

I claim} An airline oiler comprising a casing having a threaded aperture, a passageway for pressure fiuid through said casing, a reservoir for oil surrounding said passageway, a pin loosely mounted transversely to said fluid pressure passageway having one end supported by the bottom wall of said passageway and the other end projecting ihrrmgh said passageway and into said oil reservoir, a second pin loosely i mounted transversely to said passageway having one end supported by the bottom Wall of said oil reservoir and the other end extending through said passageway and into a plug threaded into said casing, both otsaid pins being actuated transversely of said passageway for carrying oil from said reservoir into said passagevvay and'means to limit the longitudinal movement of said pins.

In testimony whereof I have signed this specification. I
